A 40 pound bag of topsoil will
cover a surface area of 12 square
feet.
a. How many pounds of topsoil are
needed to cover a surface area of
480 square feet?
b. How many bags of topsoil must
be purchased to cover a surface
area of 480 square feet?
For number of bags, divide total area by the area 1 bag can cover.
480 / 12 = 40 total bags.
Now for total weight, multiple total bags by weight per bag:
40 bags x 40 pounds = 1,600 total pounds.
A = 40 bags
B = 1,600 pounds
Jerome currently has an account balance of $1,859.55. His initial deposit on the account was $825 and it earned 5.7% simple interest. How long has Jerome held the
account?
Answer:
22 years
Step-by-step explanation:
Well we know the formula for simple interest is
I = PRT
I = interest earned
P = initial balance
R = rate
T = time
We want to solve for time here....so rearrange for T
T= I/(PR )
We have
P = 825
R = .057
And I = current balance - initial balance = 1859.55 - 825 = 1034.55
So plugging all those in we have
T = 1034.55/(825×.057 )
T = 1034.55/47.025
T = 22
It was held for 22 years.
Name five fractions between 6/7 and 9/10
Answer:
43/50, 22/25, 111/125, 1111/1250, and 179/200.
Step-by-step explanation:
6/7 = 0.8571428571
9/10 = 0.9
The fractions can be anywhere within that range.
The first fraction I would name would be a fraction that equals 0.86. 0.86 = 86/100 = 43 / 50.
The second fraction can be a fraction that equals 0.88. 0.88 = 88 / 100 = 44 / 50 = 22 / 25.
The third fraction will equal 0.888. 0.888 = 888 / 1000 = 444 / 500 = 222 / 250 = 111 / 125.
The fourth fraction will equal 0.8888. 0.8888 = 8888 / 10000 = 4444 / 5000 = 2222 / 2500 = 1111 / 1250.
The fifth fraction can equal 0.895. 0.895 = 895 / 1000 = 179 / 200.
Hope this helps!

The admission fee at a carnival fair is $4.50 for children
and $8.00 for adults. One day, 2200 people attended the fair
and $5050 was collected. How many children and how many
adults attended?
Lets say:
c= number of children
a= number of adults
Answer:
Adult=1,385.71
Children=814.29
Approximately
Adult=1386
Children=814
Step-by-step explanation:
c= number of children
a= number of adults
Admission fee for children=$4.50
Admission fee for adults=$8.00
Total attendees=2200
Total amount realized=$5050
We need two equations to solve the two unknowns
c + a=2200 (1)
4.50c + 8.00a=5,050 (2)
From (1)
c + a=2200
c=2200 - a
Substitute c=2200 - a into (2)
4.50c + 8.00a=5,050
4.50(2200 - a) + 8.00a=5050
9900 - 4.50a +8.00a=5050
Collect like terms
9900-5050= -4.50a+8.00a
4,850=3.5a
Divide both sides by 3.5
1,385.71=a
Substitute a=1,385,71 into (1)
c + a=2200
c+1385.71=2200
c=2200-1385.71
=814.29
c=814.29

Answer:
The answer is option BStep-by-step explanation:
To find the side adjacent to the 50° angle we use tan
[tex] \tan( \alpha ) = \frac{opposite}{adjacent} [/tex]
From the question
The opposite is 6m
The adjacent is ?
So we have
[tex] \tan(50) = \frac{6}{?} [/tex]
[tex]? \tan(50) = 6[/tex]
[tex]? = 6 \times \frac{1}{ \tan(50) } [/tex]
But
[tex] \frac{1}{ \tan(x) } = \cot(x) [/tex]
So we have
[tex] \frac{1}{ \tan(50) } = \cot(50) [/tex]
Substitute it into the expression
That's
We have the final answer as
[tex]? = 6 \cot(50) [/tex]
Hope this helps you
=====================================================
Explanation:
We're given an opposite side and an adjacent side. The tangent rule ties these two sides together. "tangent" is nowhere to be found in any of the answer choices, but cotangent is. Recall that
cot = 1/tan
which means
tan = opposite/adjacent
cot = adjacent/opposite
one is the reciprocal of the other
-----------
This means
cot(angle) = adjacent/opposite
cot(50) = x/6
6*cot(50) = x
x = 6*cot(50)

Step-by-step explanation:
The equation of the parabola is y = (x - 1)² - 4. Then the vertex of the parabola is at (1, -4) and the parabola passes through (0, -1) and (0, 3).
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The equation is given below.
y = (x + 1)(x - 3)
We know that the equation is a parabolic equation.
And the value of y at -1 and 3 is zero.
The equation can be written as
y = x² - 2x -3
y = (x - 1)² - 4
And the vertex of the parabola is at (1, -4).
The graph is shown below.

Find the m∠RLU. A. 20 B. 42 C. 84 D. 10
Answer:
b is the correct answer. p is 10
The value of m∠RLU = 10.
How to estimate the value of m∠RLU?Given: (5p - 8) and (2p + 22)
Simplifying both of the equation, then we get
5p - 8 = 2p + 22
Add 8 to both sides of the equation, then we get
5p - 8 + 8 = 2p + 22 + 8
simplify
5p = 2p + 30
substract 2p from both sides of the equation
5p - 2p = 2p + 30 - 2p
3p = 30
p = 30/3
p = 10.
m∠RLU = 10

Justify your answer mathematically. Part B: If the school district wants to award the school with the highest average attendance, which school should it choose and why? Justify your answer mathematically.
Answer:
(A) It should choose High school Z for the most consistent attendance among its students.
(B) It should choose High school W with the highest average attendance.
Step-by-step explanation:
We are given the data for attendance in the table below, where Low represents the fewest days attended and High represents the most days attended for a single student.
School Hight School W High School X High School Z
Low 108 112 130
High 180 180 180
Range 72 68 50
Mean 169 160 162
Median 150 124 151
IQR 47.5 49.5 39.5
S.D. (σ) 29.5 32.4 27.5
(A) It is stated that the school district wants to award the school that has the most consistent attendance among its students.
Now, to check which high school should it choose; we will look for the standard deviation (σ) of each of the three schools because consistency is measured through standard deviation and the school with the lowest standard deviation means that it has the most consistent attendance among its students.
So, after looking at the standard deviation of all the three schools; the High School Z has the lowest standard deviation of 27.5.
This means that it should choose High school Z.
(B) It is stated that the school district wants to award the school with the highest average attendance.
Now, to check which high school should it choose; we will look for the Mean of each of the three schools because average is measured through mean of the data, and the school with the highest mean means that it has the highest average attendance.
So, after looking at the Mean of all the three schools; the High School W has the highest average of 169.
This means that it should choose High school W with the highest average attendance.

Jordan is solving this system of equations: y = 2x2 + 3 and y – x = 6. Which statements are true about Jordan’s system? Check all that apply. The quadratic equation is in standard form. Using substitution, the system of equations can be rewritten as 2x2 – x – 3 = 0. There are two real number solutions. There are no real number solutions. A solution of the system of equations is (–1, 1.5).
Basically the first three items are true, with the rest false.
=========================================================
Explanation:
Let's go through each answer choice one by one to see if it is true or false.
---------------------
A. The quadratic equation is in standard form.
This is true. Standard form for quadratics is y = ax^2+bx+c. In this case, a = 2, b = 0, c = 3. It might help to write the equation as y = 2x^2+0x+3.
---------------------
B. Using substitution, the system of equations can be rewritten as 2x2 – x – 3 = 0.
This is true. Start with y-x = 6. Replace y with 2x^2+3 and we get
2x^2+3-x = 6
From here we subtract 6 from both sides
2x^2+3-x-6 = 6-6
2x^2-x-3 = 0
---------------------
C. There are two real number solutions.
This is true. When you graph the two equations (I recommend GeoGebra but Desmos is another good tool), you'll see they intersect at two different locations. Each location is a solution in the form (x,y).
---------------------
D. There are no real number solutions.
This is false. It contradicts choice C.
---------------------
E. A solution of the system of equations is (–1, 1.5).
This is false. The two solutions are (-1, 5) and (1.5, 7.5) which is where the two graphs intersect.
Another way to check is to plug x = -1 into either equation. You'll find the result to both is y = 5 instead of y = 1.5
